What makes BucketMate different?

It only does S3, and it does it in depth. Each provider gets its own setup and features, like AWS SSO, R2 custom domains, MinIO on localhost, and B2 version cleanup. All of it sits behind a clean, modern interface that stays simple for everyday work.

Does BucketMate mount S3 as a drive like ExpanDrive?

No. BucketMate is a dedicated S3 app. You drag files between Finder and your buckets, and preview files with Quick Look.

Which providers does BucketMate support?

AWS S3, Cloudflare R2, MinIO, Wasabi, Backblaze B2, DigitalOcean Spaces, Supabase Storage, Hetzner Object Storage, Tigris, and Google Cloud Storage, each with its own setup. Any other S3-compatible endpoint works too.

Does BucketMate run on Linux or Windows?

Not as a desktop app, but the BucketMate web app runs in any modern browser on Windows and Linux.

How much does BucketMate cost?

There is a free plan for personal use. Pro is a one-time purchase: $29 for Mac, $19 for iPhone, or $39 for Universal (Mac, iPhone, and Web), with lifetime updates.
